Abstract

Electromagnetically controllable microbodies whose optical properties may be altered by changing their orientations are useful in imaging and display devices. Disclosed is a method of microbody masking using vacuum vapor deposition technology comprising placing the microbody in the path of a vaporized beam and coating to a desired thickness. Various plating schemes may be devised and their configuration adjusted to meet a given end. Additionally, ion plating via various grid controls, for example, may be used for other than hemispherical coating. Alternatively, screens may be used as masks for partial coatings. The plating technique may produce the final composite directly. An inert mask such as gold may be deposited on a previously iron coated glass sphere. Subsequent acid etching of the unmasked iron would lead to hemispherical magnetic coat.
